Sannikov Land
Sannikov Land (Russian: Земля Санникова) was a phantom island in the Arctic Ocean. Its supposed existence became something of a myth in 19th-century Russia.
Yakov Sannikov and Matvei Gedenschtrom claimed to have seen it during their 1809–1810 cartographic expedition to the New Siberian Islands. Yakov Sannikov was the first one to report the sighting of a "new land" north of Kotelny Island in 1811 (hence, the name "Sannikov Land").
In 1886, a Baltic German explorer in Russian service, Baron Eduard Toll, reported observing the elusive land during an expedition to the New Siberian Islands. In August 1901, during another expedition led by Toll, The Russian Polar Expedition, Russian Arctic ship Zarya headed across the Laptev Sea, searching for the legendary Sannikov Land (Zemlya Sannikova) but was soon blocked by floating pack ice in the New Siberian Islands. During 1902 the attempts to reach Sannikov Land, deemed to be beyond the De Long Islands, continued while Zarya was trapped in fast ice. Leaving the ship, Russian Arctic explorer Eduard Toll and three companions vanished forever in November 1902 while travelling away from Bennett Island towards the south on loose ice floes.
